[PATCH 0/2] KVM: x86: avoid using stale x86_emulate_ctxt->intercept value

[Vitaly Kuznetsov]

After commit 07721feee46b ("KVM: nVMX: Don't emulate instructions in guest
mode") Hyper-V guests on KVM stopped booting and tracing shows that we're
trying to emulate an instruction which shouldn't be intercepted. Turns out,
x86_emulate_ctxt may hold a stale 'intercept' value.

This is a regression in 5.6-rc4 and I'm marking PATCH1 for stable@. The
commit 07721feee46b ("KVM: nVMX: Don't emulate instructions in guest mode")
is, however, correct, it just seems to reveal a pre-existing condition.
